I have installed and bootable usb with ubuntu 16.04.4 LTS. I have changed to UEFI mode. First of all, I directly ask for install UBUNTU, then when it took like 2 hours I poweroff.
Then I tried to "try ubuntu without installing" and It happens the same. What should I do ?
Also I cheked if there is any error, it says no, then it says presss enter and I get something like this. namespace lookup failure linux ae_not_found psargs-364
More info: I have already the latest version of UEFI/BIOS, and I downloaded ubuntu with grub2.
